"Arlene"--the electronic Roto-Extractor assistant

Using an analysis of the surgical assistant's manual aspiration functions as a guide, an electronic Roto-Extractor surgical assistant has been developed that is entirely subservient to the surgeon's foot control. The electronic assistant communicates audibly to the surgeon regarding the interplay of actual fluid flow and the accumulation or build up of vacuum in the aspiration lines of infusion-aspiration-cutting instruments.
